Defensive publication

ABSTRACT

AN ARTICLE OF MANUFACTURE COMPRISED OF A SHAPED ARTICLE FORMED OF A HYDROPHOBIC MATERIAL WHICH IN DRY CONDITION NORMALLY TENDS TO DEVELOP STATIC CHARGES OF ELECTRICITY THEREON, THE SURFACE OF THE MATERIAL CARRYING ADHERED THEREON, FOR PURPOSE OF REDUCING THE TENDENCY OF THE ARTICLE TO DEVELOP STATIC CHARGES,A CONDUCTING RANDOM COPOLYMER HAVING THE STRUCTURE:   -((CH2-(1,1-DI(CH3-)PIPEPIDIN-3,5-YLENE)X-(CH2-CH(-CO-NH-   C(-CH3)2-CH2-CO-CH3))Y)N- . (Z(-))N   WHEREIN X AND Y ARE VARIABLE INTEGERS OFF 1 OR GREATER AND Z IS AN ANION. NORMALLY, THE RANDOM COPOLYMER WILL BE PRESENT IN THE AMOUNT OF ABOUT 0.1 TO 3.0 WEIGHT PERCENT HOWEVER, THE PREFERRED RANGE IS IN THE AMOUNT OF 1.0 TO 2.0 WEIGHT PERCENT. ALSO, THE INVENTION ENCOMPASSES A PROCESS FOR TREATING TEXTILE MATERIALS COMPRISING HYDROPHOBIC FIBROUS MATERIALS WHICH IN DRY CONDITION NORMALLY TENDS TO DEVELOP STATIC CHARGES OF ELECTRICITY THEREON, SAID PROCESS COMPRISING APPLYING TO SAID TEXTILE MATERIAL A CONDUCTING RANDOM COPOLYMER HAVING THE STRUCTURE SET FORTH ABOVE, AND CURING SAID CONDUCTING COPOLYMER BY HEATING AT A TEMPERATURE OF ABOUT 80* TO 170* C. FOR 1 TO 15 MINUTES. FURTHER, THE INVENTION ENCOMPASSES THE COPOLYMER BEING APPLIED AS AN AQUEOUS SOLUTION COMPRISING CONDUCTING COPOLYMER PRESENT IN THE AMOUNT OF 1 TO 5 WEIGHT PERCENT, HYDRAZINE HYDRATE PRESENT IN THE AMOUNT OF ABOUT 1 WEIGHT PERCENT, AND WATER PRESENT IN THE AMOUNT OF 98 WEIGHT PERCENT.

C08j 1/44 U.S. Cl. 117-1395 No Drawing. 25 PagesSpecification An article of manufacture comprised of a shaped articleformed of a hydrophobic material which in dry condition normally tendsto develop static charges of electricity thereon, the surface of thematerial carrying adhered thereon, for the purpose of reducing thetendency of the article to develop static charges, a conducting randomcopolymer having the structure:

wherein x and y are variable integers of 1 or greater and Z is an anion.Normally, the random copolymer will be present in the amount of about0.1 to 3.0 weight percent. However, the preferred range is in the amountof 1.0 to 2.0 weight percent. Also, the invention encompasses a processfor treating textile materials comprising hydrophobic fibrous materialswhich in dry condition normally tends to develop static charges ofelectricity thereon, said process comprising applying to said textilematerial a conducting random copolymer having the structure set forthabove, and curing said conducting copolymer by heating at a temperatureof about 80 to 170 C. for 1 to 15 minutes. Further, the inventionencompasses the copolymer being applied as an aqueous solutioncomprising conducting copolymer present in the amount of 1 to 5 weightpercent, hydrazine hydrate present in the amount of about 1 weightpercent, and Water present in the amount of 98 to 94 weight percent.
